A new video has been released in celebration of the singer's 70th birthday AND the 50th anniversary of his songwriting partnership with Bernie Taupin.
The loved-up couple took the tube to Rod's big performance at London's O2 Arena.
Rod Stewart may have been knighted last year, but that doesn't mean he has developed any airs and graces.
In fact, the singer and his wife Penny Lancaster travelled on public transport to his concert at London's O2 Arena on Monday evening.
Penny, 45, uploaded two pictures of herself with the 72-year-old rocker riding around on London's tube network.
Captioning the pictures of the pair disguising themselves in oversized black coats and dark sunglasses, she wrote: "Sneaking into London by train today ... From the overground to the Underground!! (sic)"
The pair were heading to the O2 Arena for Rod's final show of his tour before he takes a break from performing until June.
He's then set to perform two exclusive shows in Shrewsbury and Durham, before headlining the Isle of Wight Festival.
